.W ECIFICATION forming part of Letters Patent No. 315,957, dated April 14, 1885.

To [LZZ whom it may concern.-

Be it known that I, EDWIN NORTON, a citizen of the United States, residing-in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Street Lamps for Burning Gasoline,of which the following is a specification.

. My invention relates to gasoline street-lamps; and its object is to provide a street-lamp for burning gasoline, of asimple, cheap, and durable construction that will be selfcxtinguishing, and will also obviate the necessity of nightly carrying around the gasoline tank or can to replenish each lamp; and to this end my invention consists of a street-lamp furnished with a reservoir or tank adapted to hold enough gasoline to burn a number of nights, so that it will only require to be refilled once in, say, for example, every two weeks, and provided with a supplemental tank or reservoir from which the burner is supplied, and which contains only the quantity of gasoline necessary to burn the required number of hours each night, so that the lamp will be extinguished at the proper time by the failure of the supply. The supplemental tank is conncoted with and tilled from the main reservoir. The glass case or chamber surrounding the burner is or may be of any usual or suitable construction. The main reservoir I place at the base of the lamp to give the structure strength and rigidity, and to prevent its being top-heavy, as well as to protect its contents from the heat of the burner. The base of the reservoir is furnished with a socket to receive the end of the lamp-post. The supplemental tank is attached to the lamp-frame in any suitable manner above the burner, and

is connected by a pipe or tube with the main reservoir. This tube should extend to near the bottom of the main reservoir, and it is furnished with a cook or check-valve to close the same when the supplemental reservoir has been filled. As the main reservoir is located below the supplemental, the latter is filled by pumping air into the upper part of the main reservoir, whereby the air is compressed and the liquid forced up into the supplemental tank. For this purpose a tube furnished with a stop-cock is provided, leading from near the top of the main reservoir, and to which the rubber tube of an ordinary air-pump may be connected.

In the accompanying drawings, which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a central vertical section of a device embodying my invention, the section being taken diagonally through two opposite corners of the lampframe; and Fig. 2 is a similar view showing a modification adapted to burn kerosene or other oil, which may be supplied to the burner from below. Fig. 3 shows a modified form of the supplemental reservoir in which it is divided into two distinct cans, the upper one of which is removable.

In said drawings A represents the lamppost, and B is the main reservoir, provided with a socket, b, in its base to receive the end a of the lamp-post, and. whereby the lamp is secured thereto.

C is the supplemental reservoir secured to the metallic frame e of. the lamp, preferably by being soldered thereto at each end.

E E represent the glass sides of the lamp case or chamber, and E thedoor.

D is the burner, which is fed from the sup plemental reservoir C through the supplytube (1. The tube (1 is provided with a cock, (1, for closing the same and turning out the light. The supplemental tank C should ordinarily hold about one pint of gasoline, which will burn, usually, about eight hours with the ordinary burner used in such lamps. The size of the tank C can be of course varied to make the lamp burn a shorter or longer time each night, as may be required. The supply-tube d leads from near the bottom of the tank C.

Asecondsupplytube, (1 leading from about the middle of the tank C, may be employed, when desired, by closing the cock d in the pipe d, and thus cause the lamp to burn four instead of eight hours.

The tank C is provided with a tube, 0, furnished with acock, 0, through which tube Said tank is filled from the main reservoir B, the tube extending to near the bottom of the same, so that its entire contents may be expelled.

The reservoir 13 is provided with an airpipe, 0 leading from near the top thereof out through its bottom, and furnished with astop- I In Fig. 3 it will be observed that the sup- 65 cock, whereby the reservoir is closed tight and any evaporation of the gasoline prevented.

Fis an ordinary air-pu1npsuch, for example, as those used by plumbers and gas-fittersprovided with a rubber tube, f, which is connected to the end of the air-pipe 0 By pumping air into the reservoir B the liquid therein will be forced up into the tank 0 until the same is filled, when the cock 0 is turned and the lamp ready for use. The tank O is provided with a small vent,

0*, near its top, which also serves as a telltale to indicate when the tank is filled.

The metallic frame e of the lamp is soldered or' rigidly secured to the top of the reservoir B.

My invention is also adapted to the use of other fluids than gasoline, and in Fig. 2 Ihave shown a modification adapted to the use of kerosene or other oil. In this form the reservoir C may be preferably located in the main tank B, near its top. The opening 0 serves here as an overflow.

While the lamp-lighter will ordinarily carry the little air-pump F around with him each night, it should be observed that as the tank B is air-tight it may be charged at one time with enough compressed air to fill the tank 0 several times, so that the air-pump need not always be employed every night.

The reservoir B should preferably be-made to contain about two gallons, which amount willlast about two weeks, ordinarily, burning, say, eight hours each night; but of course the capacity of said reservoir may be varied to suit. The reservoir is filled through a screwnozzle opening, b, in its top.

In Fig. 3 I have shown the supplemental tank 0 divided into two distinct and separable parts or cans, the upper part, G, being con nected to the lower can, 0, by ahollow screwnozzle coupling, 0 0, so that the contents of the upper can can flow into the lower one. In the winter season, or when it is desired that the lamp should burn, say, eight hours, bot-h cans are filled; but in the summer, when the lamp is not required to burn so long, .the upper can,O', is removed, and the nozzle-opening 0 in the can 0 is then closed by the screwplug a, which has a vent opening, c, therein. A rim, O is soldered to the can 0 and fits over the can 0 to brace and render the connection between the two rigid and strong, as well as to protect the screw-connections from the weather and give the cans O C the appearance of a single can or tank. A disk or diaphragm, a is secured across the end of the can, just beneath the vent-opening c, to pre vent the pressure of the liquid in filling the supplemental tank from causing the same to issue too freely atthe vent before the stopcock 0 can be turned.

ply-pipe d connects with the filling-pipe c, instead of directly with the tank 0. The construction shown in Fig. 3 I deem the most improved and preferable mode of practicing my invention.

I do not herein claim, broadly, a supplytank, 0, of dual capacity, nor such tank when made in two distinct parts, connected together by screw-nozzle couplings, as I am aware that the same are old, and are shown in the Patents N 0. 143,000, to Eyrse, and No. 286,211, to Mack.

I claim 1. The combination of burner D, main reservoir B, located below the burner and. adapted to contain compressed air,'the supplemental tank 0, located over said main reservoir, and apipe connecting the reservoirs,througl1 which oil is forced from the main reservoir by compressed air therein to the supplemental reservoir, substantially as specified.

2. The combination of main reservoir B, having socket b, supplemental tank 0, fillingtube a, supply-pipe d, and air-pipe c substantially as specified.

3. The combination of post A- with reservoir B, having socket b, tank 0, pipe 0, furnished with cock 0, supply-pipe (1, burner D, air-pipe c and air-pump F, having tube f, connected to said air-pipe, substantially as specified.

4. The combination, in a street-lamp,of main reservoir B, secured on top of the lamp-post, and provided with air-pipe 0 with air-pump having tube f, connected to said air-pipe, and reservoir 0, located above said reservoir B, and provided with a pipe, 0, leading to reservoir B. substantially as specified.

5. The combination of post A with reservoir B, having socket b, to receive the end of the post, and metallic lamp-frame e, rigidly secured to the top of said reservoir B, substantially as specified.

6. The combination of main reservoir B, with supplemental" tank 0, located above, con- 11o nected with, and filled from said main reservoir by pressure of air therein, vent-opening c, and disk or diaphragm c beneath said vent, substantially as and for the purpose specified.

7. The combination of main reservoir B, supplemental tank 0, connected with said main reservoir, a removable can or chamber, 0, having a hollow screw-nozzle coupling, 0 c, and burner D, having a supply-connection 120 with said tank 0, substantially as specified.
